delay the removal of this symbol export by one more kernel release,
giving external modules such as VirtualBox a chance to stop using it.

is largely pointless as without a lot of work only the most
trivial of Solaris binaries can work with the emulation code.

+---------------------------

+What: init_mm export
+When: 2.6.26
+Why: Not used in-tree. The current out-of-tree users used it to
+ work around problems in the CPA code which should be resolved
+ by now. One usecase was described to provide verification code
+ of the CPA operation. That's a good idea in general, but such
+ code / infrastructure should be in the kernel and not in some
+ out-of-tree driver.
